i dont think that you can, each game usually stays in the original region it was made in
No but in Pokemon crystal you can go from johto to kanto to johto etc.!!!
You have to complete your Hoenn Pokedex. After you get the diploma go to a PC at and youll find a Johto pass. Go on the Ferry and they'll take you to the Johto region. I don't know if this works; I haven't tried it yet. My friend told me it ONLY works for Emerald.
you dont
Hoenn is the only accessible region in pokemon Ruby, Sapphire, and Emerald
You can only get the Johto starters by trading from Emerald or XD.
U get all the Pokemon you can't go to the johto region in pkmn ruby/Sapphire you can only do that in Pokemon emerald
You have to get all gold symbols at the Battle Frontier. Then you will het a call from Prof. Birch telling you to go to the S.S. Aqua which will send you to the Johto region.
I don't think you can
You can`t it`s imposible exept in Emerald. I've heard that in Emerald after you get the diploma from the game designer in the Lilycove Motel you go to a PC in any center and a Johto Pass will be there.Then go to the cruise in Lilycove and she`ll take you to the Johto Region.I read this somewhere else and I'm trying it myself. PS. You get the diploma after completing the National Pokedex
you trade with others who has the kanto, johto, or other hoen regions
The secret of celebiWell the only way to get to the Johto region is to finish your hoenn pokedex. After you get the diploma go to a PC at a center and youll find a Johto pass. GO on the Ferry and they'll take you to the Johto region. Rumors had said that in Johto theres this place called Whirl Islands. I believe if your lucky enough you can find a celebi there!!! Its true my friend has a celebi!!!!!!!!!!!!!
You cant unfortunately. 8(
